I used a Fizik Airione on my TT bike. I liked it at first, and then decided, um, not as much.

My ne Specialized TT bike came with a saddle from Specialized that I really like. I'll have to look up what it is and get back to you. I know that DH didn't like his though (which is ok, since I stole it and put it on another one of my rides instead ).

I tend to be on the nose of my saddle A LOT during the TT, so cutouts and whatnot are more irrelevant than on my regular road or MTB saddles. A skinnier nose with some padding seems to be key.
